Description
The CRD35L01 demonstrates the CS35L01 high-effi-
ciency Hybrid Class-D audio amplifier. This reference
design implements a single-channel amplifier that deliv-
ers 1.7 W per full-bridge channel into 8- ? loads using a
single +5-V supply.
Differential audio inputs can easily be connected
through the J1 header. If desired, the gain can be ad-
justed through the optional input resistors.
The -SD, -FSD, -HD, or -FHD suffix designates the
CS35L01’s operational mode. Each of the four boards
is configured to operate in each of the four correspond-
ing modes of the CS35L01 device.
Device shutdown control is available through the J2
header.
